Jock and Jim were a couple of drinking buddies who worked as airplane mechanics in Glasgow. One day the airport was fogged in and they were stuck in the hangar with nothing to do.

Jock says, "Man, I wish we had something to drink!" Jim says, "Me too. Y'know, I've heard you can drink jet fuel and get a buzz. You wanna try it?" So they pour themselves a couple of glasses of high octane hooch and get completely smashed.

The next morning Jock wakes up and is surprised at how good he feels. In fact he feels GREAT! NO hangover! NO bad side effects. Nothing! Then the phone rings... It's Jim.

Jim says, "Hey, how do you feel this morning?" Bud says, "I feel great. How about you?" Jim says, "I feel great, too. You don't have a hangover?" Jock says, "No, that jet fuel is great stuff -- no hangover, nothing. We ought to do this more often." "Yeah, well there's just one thing..." "What's that?" "Have you farted yet?" "No....."
